Rocker arms can break for several reasons:
Material Fatigue: Over time, constant stress and movement can weaken the metal of the rocker arm, leading to a break.
Improper Installation or Adjustment: If the rocker arm isn't installed correctly or isn't adjusted properly, it can experience excessive stress, leading to breakage.
Excessive Engine Load: If the engine is subjected to extreme conditions or if there's a sudden spike in load (like aggressive acceleration), it can put undue stress on the rocker arm, causing it to break.
Lack of Lubrication: Proper lubrication is crucial for the smooth operation of engine components. If the rocker arm doesn't receive adequate lubrication, it can wear out quickly and eventually break.
Manufacturing Defects: In rare cases, a rocker arm may have a defect from the manufacturing process, leading to premature failure.
Identifying the specific cause often requires inspection by a qualified mechanic or engineer familiar with the engine design and operation.
